Church of the Holy Apostles - Column Capital #3 (3D)
|
|
This is a 3D model at various resolutions (ultra low, low, medium, high, RAW) of a Corinthian column capital from the western facade of the church of the Holy Apostles.
The church, a UNESCO World Heritage Monument, is situated in the homonymous square in Thessaloniki, in the beginning of the modern Olympou Street. It lies south of the decumanus (Saint Demetrius Street), around 50 meters from the west city wall, near the Litea Gate, ruined today. Originally it was the katholikon (main church) of a sizeable monastery. Except for the church, little evidence remains still today from the original complex, such as parts of the precinct, a gateway to the south of the katholikon and a large cistern to its northwest. Initially the monastery covered an area of more than 10.000 square meters.

| Name | Ultra Low resolution 3D model of the Church of the Holy Apostles - Column Capital #3 |
| Description | This is a ultra low resolution 3D digital replica of the Church of the Holy Apostles - Corinthian Column Capital that is situated in the homonymous square in Thessaloniki, in the beginning of the modern Olympou Street. It lies south of the decumanus (Saint Demetrius Street), around 50 meters from the west city wall, near the Litea Gate, ruined today. Originally it was the katholikon (main church) of a sizeable monastery. Except for the church, little evidence remains still today from the original complex, such as parts of the precinct, a gateway to the south of the katholikon and a large cistern to its northwest. Initially the monastery covered an area of more than 10.000 square meters The monument was selected to be 3D digitised within the framework of the European Commission funded 3D-ICONS project by the Athena RC Xanthi's Division. It's exterior was captured in 3D using the Structure-From-Motion (SFM) and Dense Multi-View 3D Reconstruction (DMVR) methods. Aerial and terrestrial photoshooting sessions were performed during the winter of 2014 always during cloudy days. A total of four digitisation sessions were performed where each resulted a number of image sequences presenting the monument from different points of views. The terrestrial photoshooting sessions were implemented using camera tripods and custom monopods (3m-9m adaptive). We attempted to keep the distance between two terrestrial photoshooting points at 60cm. All aerial photoshooting was performed using a custom hexacopter equipped with gimbal remote controlled two axis tilt-roll camera base, first-person view (FPV) and GPS. A pair of Samsung NX1000 20MP compact DSLR cameras with fixed 16mm and 20-50mm lenses were used. Agisoft PhotoScan (ver. 1.1) has been used for the production of monument's 3D digital replica. Although, flight paths were designed they have been performed manually due to bad GPS reception (high buildings around the monument). Furthermore, the calibration of the cameras was performed by the software itself. A total of 4090 photos were used to generated the 3D model. The processing of the image sequences was performed on two computer systems (CPU IntelCoreI74820K 3.7Ghz, 64GB RAM, Radeon R9 290X, Microsoft Windows 7 64-bit). Additionally, empirical measurements between strong (in terms of visibility) feature points on the surface of the monument were performed and used to scale the 3D model. The model is aimed for visualisation purposes in low end hardware and it is stored in the X3D file format that carries colour information using the texture mapping approach. It has been digitised using a multi-image based 3D reconstruction approach (Structure from Motion/Multi-Image Dense Stereo 3D Reconstruction). |
